LIQUID MEASURNG AND DISPENSJTG- FPARATUS.

Application filed August 8, 19,24. Serial No.

My invention relates to liquid measuring and dispensing apparatus ot' the so-called visible'type and particularly to means :tor adjusting' the height Within the visible containe'r et a vertical pipe l'rom which the liquid to be dispensed is drained bacl; to the desired level so that when the service valve is opened peinnittingl the dispensing' ot' the contents ott the visible container, the enact quantity desired will be in the container ready to be dispensed. This general type o" apparatus is in common use for dispensing gasoline at street curbs or lilling` stations.

The principal object ot my invention is to provide an adjustable stop mechanism ot a simple, sturdy and convenient type in combination with the over-.tlow` pipe of a visible measuring` and dispensing apparatus.

In the particular embodiment ot my invention selected tor illustration:

Figure l is an elevation ot' a visible measuring and dispensing apparatus having a vertically adjustable overflow pipe and equipped with my improved stop mechanism7 Fig. 2 an enlarged detail, is a side view partly in elevation and partly in section of the stop-rod, the adjustable stops thereon and the strike-bolt mechanism,

Fig. 3 an enlarged detail is a perspective of the strike-bolt mechanism With the overiiow pipe in horizontal section, and astop with its threaded rod and sealing rods in horizontal section, and

Fig. 4.- is a 'cross section on the line i-4: of Fig. l.

Referriiig now to the drawings, A is the housing of a gasoline measuring` and dispensing mechanism suitable lior out-door use with a vertically sliding door, o1, provided With a handle a2. The housing is surinounted by a cylindrical transparent container B Within which terminate the lill-pipe C and the overivlow pipe l), and the gasoline is dispensed to customers thru the valve controlled outlet F. Liquid is pumped from a source ot supply not shovvn by any pump as E.

The overflow pipe D as shown in Fig. l., is set to drain back to the source ot supply7 enough ot the gasoline that has been pumped into the container l5, so that just tour gallons remain therein to be dispensed at that setting.

The pipe B is moved up and down through the usual stun-ting' bones by hand by means of handles c7 secured to a strike-bolt mechamsm li. consisting ot a housing 7c, clamped at its rear by clamp 751, rentorced by pin leg, and a forward portion terminating in a forli having preferably a short arm 7c3, and a long arm ist from between which may be projected or retracted a strike-bolt Ibi. lWhen the door o is closed a locl o3 has a bolt o4 adapted to be projected over the end of thelong arm ict and hold said door shut, until unlocked. The bolt ,t5 is moved in and out by means ot a shalt la@ to either end of Which is lined a handle le? having preferably the general shape ol adoor knob. To this shattc is lined a double end lever 738, one end ot which has a t'orl; 'J in which is loosely seated a pin i210 secured to the bolt fc5. so that rotation ot the shaft 7c in a clock-l wise direction (see Fig. 2) moves the boltoutwardly toward the stop-rod` Gf but this outward movement is limited by the other end 7011 ot' the lever 738 contacting,` With the pin k12 secured to the housingla. Rotation ot the shaitt 7e in the opposite direction Will retract the' bolt its until it contacts with the overflow pipeD. lil is an oil-cup.

Parallel with the overilovv pipe l) and preferably directly in iront of it7 is secured the threaded stop-rod G With a plurality ot" stops threaded thereon adapted to be adjusted as to height rotation. Each of the stops g, g4, g5, g, Q7, g8 have vertical grooves gg thru the periphery, preferably one foreach quarter turn, and sealing rods g1, g2 are adapted toseat in them when adjusted and prevent their beine" rotated out oi prop-er posit-ion by accident or the design of malicious or l'nischievou's persons. These rods are removable and may be sealed in position by sealers ot Weights and measures in the usual Way.

lilhen the apparatus is assembled for use the rods g1, g2 and G and the stops on the latter lie between the arms 7:3 and Zit of the torlr and. the strike bolt mechanism l and attached overflow pipe l) are free to be raised or lowered at Will as longl as the bolt is retracted. The stop g3 is set tor complete draining outl the container l, when the strike bolt les contacts with and rests on its top, and' so limits the descent of the pipe l). Stop g4 is set to retain one lgallon tor deliv ery through outlet l?, that is the surface ot the liquid stands level With the (l) on the container B when the bolt 7:3 strikes and comes to rest on its top. Stop g is set to retain two gallons for delivery thru outlet l?, that is the surface ol the liquid stands level with the (2) on the container B when the bolt 7.,'5 strikes and comes to rest on its top. Stop gs is set to retain three gallons for delivery through outlet F, that is the surface ot the liquid stands level with the (3) on the container B when the bolt 705 strikes and comes to rest on its top. Stop g7 is set to retain tour gallons for delivery through outlet F, that is the sur'l'ace of the liquid stands level with the (fl) on the container B, when the bolt flstrilresand comes to rest on its top. Stop gs is set to retain live gallons lor delivery thru the outlet F, that is the surface ot' the liquid stands level with the (5) on the container B, when the bolt la strikes and comes to rest on its top.

lVhen the tube D is to be raised or lowered the handles k7 are lirst rotated so as to retract the bolt 765, and then with the bolt in that position the operator litts on the han dles if the tube is to be raised until the desired position, or a little above it is reached, then the handles are rotated so as to push the bolt outwardly, and it the bolt is somewhat above the level oil' the top ot the appropriate stop, the operator pushes down on the han dles until the bolt strikes and rests upon the top oi' said stop. It the tube l) is to be lowered, the bolt is retracted, the tube lowered by pressing down on the handles until the bolt has passed the stop above the one to be used, then the bolt is protruded, and the tube vfurther lowered until the bolt strikes and rests upon the top of said stop.

Many variations may be made from the mechanism shown without departing from the spirit of my invention, and all such are claimed as within the scope of the claims.

I claim as my invention and desire to secure by Letters Patent of the United States:
